The embryonic stage extends from 16 days through the end of week 8.

The liver in a newborn (neonate) plays a crucial role in metabolism, detoxification, and the production of vital proteins and enzymes. However, the liver itself does not process food, extract nutrients, or eliminate residue in the context of digestion. These functions are primarily carried out by the digestive system, including the stomach, intestines, and other associated organs. Therefore, this statement is false.

A. The renal tubules reabsorb more water. If blood volume and pressure are too high, the body would aim to reduce them, not increase them further. Reabsorbing more water would increase blood volume.

B. The kidneys produce less urine. To lower blood volume and pressure, the kidneys would increase urine production, not decrease it.

C. ADH release is inhibited: ADH (antidiuretic hormone) promotes water reabsorption in the kidneys, leading to increased blood volume and pressure. When blood volume and pressure are too high, the body inhibits ADH release to promote water excretion and lower blood volume and pressure.

D. The renal tubules reabsorb more sodium. Reabsorbing more sodium would lead to water retention, increasing blood volume and pressure, which is the opposite of what the body needs when blood volume and pressure are already high.
